CAR JOURNAL.

asses.

Be it lrnown that l, ALBERT MELVILLE, a citizen of the United States, and a resident of Morrisville, in the county of Bucks and State of Pennsylvania, have invented a new and Improved Gar Journal, of which the following is a full, clear, and exact description. i v

The present invention relates to new and useful improvements in railway rolling stock. and it pertains more particularly to car journals.

l-ieretofore it has been the common practice in the construction of car journals to make the brasses of less length than the journal portion of the axle. This construction permits of a sliding movementof the brass longitudinally of the axle, which action is conducive to side sway of the car body well as unsteady riding thereof.

. t is one of the primary objects of the 111- vention to so construct the brass of a journal box that the same will under normal onditions have its opposite ends in operative engagement with their respective ends of the axle journal, thus reducing the tendency of the car body to sway sidewise in its travel.

It is a further object of the invention to so form the brass that it may compensate for relative changes between the axle and the journal box in taking curves and other conditions to which the several parts are subjected in ordinary use.

It is a further object of the invention to so construct the compensating brass that it may be adjusted to function at predetermined strains and stresses.

lVith the above and other objects in view, reference is had to the accompanying drawings, in which Figure 1 is a view partly in section and partly in elevation of a journal box constructed in accordance with the present invention.

Figure 2 is a detail plan view partly in section of a brass constructed in accordance with the present invention.

Referring more particularly to the drawings, the reference character 5 designates the axle and 6 designates the axle journal, said axle journal being formed with an inner shoulder 7 and an outer shoulder 8 in the ordinary manner.

The reference character 9 designates the journal box and 10 designates the brass,

which brass is retained inposition inthe ournal box by means of a key 11, as is the common practice.

by referring to Figure 2, it will be noted that the brass 10 comprises two members 12 and 13, and these members 12 and 13 are each provided with a, face 14: adapted to conform to the axle journal 6.

The member 12 of the brass is provided with two recesses 15, and the member 13 is provided with two recesses 16, the recesses 15 and 16 being so positioned in their re spective sections 12 and 13 as to occupy positions opposite to each other when the brass is placed in operative position in the journal boxes.

The block 18 is further provided with internally screw threaded passages 17, and mounted in each of said internally screw threaded passages 17 is a threaded bolt 18.

The recesses 15 and 16 are adapted to receive springs 19, and interposed between the inner end of each of the threaded bolts 18 and its respective spring 19 is a washer or the like 20.

The device operates in the following manner: The journal box 9 is assembled about the axle 5, and the brass 10 is positioned on the axle journal 6. After this has been done, the threaded bolts 18 are moved inwardly of the section 13 and the springs 19 are placed under suflicient tension to space the sections 12 and 15 of the brass until the inner section 12 engages the shoulder 7 of the axle journal 6 and the section 13 en gages the outer shoulder 8 of the axle journal 16.

By this construction, it is apparent that the sections 12 and 13 of the brass 10 entheir respective shoulders 7 and 8 and longitudinal movement of the brass relative to the axle journal is obviated. When, however, the body is placed in undue strain, as in taking curves, and longitudinal movement of the axle to a certain degree is necessary, the springs 19 will be placed under compression and such movement will be thereby permitted. By a mere adjustment of the threaded bolts 18, the point at which the sections 12 and. 13 of the brass will operate may be determined.

From the foregoing, it is apparent that the present invention provides a construction by means of which the side sway due primarily to the longitudinal sliding movement of the brass relative to the axle is able journal brass \is provided.

In a journal bearing, a brass comprising two semi-cylindricalmembers, each provided in one of its ends with recesses, and coiled springs mounted in said recesses to said brass apart, said springs permitting movement of the brass members toward each other, as and for the purpose set forth.

4. In a journal bearing, a two-part brass, coiled springs mounted between the two parts of said brass to maintain said brass members in spaced relation, and means carried by one of the parts of said brass for adjusting the tension of said springs.

5. -In a journalbearing, an axle having a journal portion, and a brass the ends of which are adapted under normal conditions to'engage the ends of the journal portion of said axle, as and for the purpose set forth.
